GASULENE AND OIL SYSTEM FUR. AUTOMOBILES.

Application filed. November 16, 1918.

T 0 rail to 720m it may concern:

Be it known that I, JULES Raucous, a c1t1- zen of the United States,res1d1ng at Grand Rapids, in the county of Kent and State,

of Michigan, have invented certain new and useful Improvements inGasolene and Oil Systems for Automobiles, of which the following is aspecification.

This invention relates to an emergency gasolene and oil system forautomobiles, and an object of the invention is to provide an auxiliarygasolene or fuel retaining tank which is carried at the forward end ofthe motor vehicle and is supplied, by gravity action, from the maingasolene supply tank of the automobile, so as to maintain a supply ofgasolene at the forward end of the ma chine for feeding to the engine ormotor of the motor vehicle when climbing a steep hill or at such othertimes that the feed of the gasolene or fuel from the ordinary rearsupply tank is not sufficient to operate the engine.

The subject matter of the present application is a continuation in partof the application for automobile body filed November 27, 1916, SerialNumber 133,591, and an object of the invention is to provide, inconnection with the emergency gasolene tank, an emergency oil reservoiror tank which is formed within the main body of the tank construction ofthe auxiliary or emergency fuel tank, and from which a supply pipe leadsfor discharging the contents of the oil reservoir into the engine sumpthrough the breather tube thereof.

Other objects of the invention will appear in the following detaileddescription, taken in connection with the accompanying drawing, forminga part of this specification, and in which drawing:

Figure 1 is a side elevation of a motor vehicle, showing parts thereofin section to illustrate the improved emergency system.

Fig. 2 is a side elevation of the emergency system looking from theopposite side of that exposed in Fig. 1.

Fig. 3 is a cross section through a part of the cowl of the motorvehicle showing the auxiliary fuel tank and emergency oil reservoir insection, and

Fig. 4c is a detailed section view through the tank illustrating themanner of connecting a filler plug to the reservoir.

Referring more particularly to the drawing, A indicates an automobile ofany de- Speeifieation of Letters Patent.

sired shape or type, which has the usual engine or motor B including thebreather tube C. The improved emergency oil and fuel system is shownapplied to the automobile and it includes the ordinary gasolene supplytank 1 which is carried at the rear end of the motor vehicle and hascommunication through a supply pipe 2 with the carbureter l) of theengine B for supplying gasolene or analogous volatile liquid to thecarbureter. The pipe 2 has a valve 3 interposed therein between the tank1 and carburetor l) to permit the cut-off of the flow of gasolenefronrthe tank to the carbureter if desired. A. branch pipe 4communicates with the pipe 2 between the tank 1 and valve 3 and itsupper delivery end has communication with the'interior of the auxiliaryor emergency reservoir or tan r 5 which is positioned near the forwardend of the automobile as clearly shown in Fig. 1 of the drawings, itbeing preferably positioned directly in front of the instrument boardindicated at 6. The gasolene from the tank 1 will flow, through the pipe1 and into the tank 5, until the gasolene in the tank 5 maintains anequal level. with the gasolene in the tank 1 and if it is so desired,the valve 7 may then be closed, for cutting off the supply of gasolenein to the tank 5. A gage 8 is associated with the tank 5, beingconnected to the pipe 1 for indicating the quantity of liquid within themain body or compartment of this auxiliary tank. An outlet pipe 9communicates with the bottom of the main compartment of the tank 5 andwith the pipe 2 between the valve 3 and carburetor D for allowing theliquids or gasolene to flow from the auxiliary or emergency tank to thecarbureter. A valve 10 is interposed in the pipe 9 near the tank .5 forcutting off the flow of the gasolene through the pipe 9.

The tank 5 has a partition 11 therein near one end, forming a reservoiror receptacle 12 for lubricating oil, and an outlet pipe 13 leads fromthe reservoir 12, having its out let end 14 positioned above and inalinement with the breather cap C of the engine l for allowing the oilfrom this emergency reservoir to How through the breather cap or tubeinto the sump of the engine in case the oil supply of the engine becomesdangerously low. A. valve 15 is interposed in the pipe 13 forcontrolling the passage of oil from the reservoir 12 into the breathertube 0.

iii

Filler plugs 19 and 20 are carried by the cowl of the automobile A andcommunicate respectively with the gasolene containing compartment of thetank and the oil reservoir 12. These filler plugs are of the ordinaryconstruction, comprising a tube 21 which extends through the cowl andthe tank 5 being adapted to receive therein the outlet of the spout of afunnel and these tubes 21 have their outer ends threaded for receiving aclosure cap 22. A gasket 23 may be interposed between the closure cap 22and p the collar which surrounds the tube 21 for forming a fluid tightjoint between the cap and tube. These filler plugs 19 and 20 arepositioned one upon each side of the cowl of the automobile so that therespectivereservoirs or compartments with which they communicatemay befilled from the exterior of the machine if desired, thereby providingfor the fillin of the tank 1 through the auxiliary tank 0, if desired,by closing the valves 3 and 10 and opening the valve T or to permit thefilling of the emergency or auxiliary tank independent of the gravityaction for filling the same from the tank 1.

It will be readily apparent,'from the foregoing description and thedrawings, that when the tank 1 is filled, the gasolene will flow bygravity, through the pipes 2 and a, when the valve 7 is opened, into thetank 5 where it will assume the same level as is maintained in the tank1 and after this level has been provided, the valves 7 and 3 may beclosed to prevent the gasolene from flowing from the auxiliary tank 5back to the tank 1 in case the gasolene level in the latter tank fallsbelow the level in the tank 5, and in cases where the automobile isgoing up a steep incline or grade, so as to prevent the proper feedingof the gasolene from the tank 1, the valve 10 may be opened to allow thegasolene to feed from the tank 5 to the carbureter D. In cases where thesupply of gasolene from the tank 1 is exhausted and it is desired to usethe gasolene from the auxiliary or emergency tank, the valve 3 is closedto prevent the gasolene from flowing backwardly through the pipe 2 intothe tank 1, and the valve 10 is opened to allow the gasolene to flowthrough the pipe 9 and to the carbureter D. If the valve 7 is leiftopen, the 8 will indicate the quantity of gasolene in the tanks 1 and 5,and in cases where the valve 7, is closed, the age will indicate onlythe quantity of gasolene in the tank 5.

Changes in details may be made withou' departing from the spirit of thisinvention, but;

I claim:

1. In a motor vehicle, the combination, of a body, a carburetcr, a rearfuel tank arranged in said body, a front auxiliary fuel tank carried bythe body and arranged in substantially the same horizontal plane withsaid rear fuel tank, a pipe communicating with said rear tank andcommunicating with the carburetor, a branch pipe connected to said firstmentioned pipe and having communication with said front auxiliary fueltank whereby the fuel will maintain equal levels in both tanks, a valvein said branch pipe near said auxiliary supply tank, and a second valvein the first mentioned pipe, between the eommunicatiou in the firstmentioned pipe with the b anch pipe and the carburetor, an outlet pipehaving); communication with said front auxiliury fuel tank and with thefirst mentioned pipe beyond the valve therein, and a valve in said outlet pipe adapted to be normally closed.

2. ln a motor vehicle, the combination of a body, an internal combustionengine ineluding a crank ease having a breather pipe and a earbureter,of a supply tank having a fuel compartment therein, and a lubrieatingoil compartment, a pipe connecting the fuel compartment with thecarburetor, and a pipe connecting the lubricating oil compartment withthe breather pipe.
